CHARLES IVI. HIGHSMITH,\ OF DENVER, COLORADO.

WINDOW-CLEANER.

To all 'whom t may concern:

Be it known' that I, CHARLES M. HIGH- siiriii, -a citizen of, the UnitedStates, residing at Denver, in the county of Denver and State ofColorado, have invented certain new and useful Improvements in lVindow-Cleaners; and I do hereby declare the v following to be afull, clear,and eXact description of the invention, such` as will enable othersskilled in the art to which it appertains to 'make and use the same.

This invention relates to windows and more especially to devices forcleaningthe.

. the cleaning of locomotive cab windows,

headlights, pilot house windows, and electric and traction car windowswith heated air. It permits no water, snow, ice, frost, steam or dust toaccumulate or remain on the said windows or headlights1 and leaves atall times an unobstructed view through the glass thereof, regardless ofweather conditions. This object is attained by means of a device placedthrough the frame, casing or sash of the glass and directing the flow ofheatedcoinpressed air against both sides lof. theglass at the same time,the mechament. Fig. 2 is an elevation of the interior of a locomotivecab, showing this attachment as applied to the windows therein, and

Fig. 3 an elevation fromthe outside of the front end of a motor car,also showing the attachment applied. Fig. lis an elevation of theattachment alone, viewed from4 theA front as seen in Fig. 1. Fig. 5 is aperspective-view showing the entire' attachment and its connections withthe cab and the boiler' of a locomotive7 anda supplemental cleaner asattached to' its headlight. Fig. 6

' is a front elevation of the headlight and :'ittachiiient on anAenlarged scale.

I have used vthe numeral 10 to designate a pane of glass mountedwithin'asash 11 which constitutes the lookout window of a locomotivecab, pilothouse, motorl car, or

the like; and the sash might be mounted to swing or to slide in theWindowframe 9 or it might be mounted directly `.within the Specificationof Lettersl Patent.

front Wall 8 of the cab. The attachment is perhaps best seen inFig. 1where it `is permanently connected with the frame 9falthough it isobvious that it might-:pass through the sash 11. It comprises inner andAouter curved pliable pipesl 1 andv 2 whereof each has its tip 3directed toward the pane of glass 10 and flattened as best seen in Fig.4, andeach has its other end connected in any suitable manner (aspermanently by soft solder` or movably' by a swivel or otherwise) withthe head 6 and the threaded end respectively of a tubular bolt 5`,\tl iel' latter being'passed through an `opei'iing-iri the frame or sash andheld therein by a nut 7 with suitablewashers if desired. lThebolt head 6is cored or bored -with a ilateral opening communicating with the axialbore through the bolt-both as shown in dotted lines--and an elbow 4:connects this lateral opening withv a supply pipe 12 through which hotor warm air under pressure is constantly supplied. This heatedcompressed air being directed in a flat stream against both sides of theglass at the same time, removes all the water, snow,

ice,'frost, steam or dust from the window,

leaving an unobstructed view through the glass at all times regardlessof weather conditions, giving the person lin charge of thelocomotive,\boat or car a clear view of the track ahead and thus'avoiding the probability of accidents on Aaccount of obstructed windowsor lookout's.

the coil. The supply pipe 12 contains a. coni trol valve 16 so that theengineer or motorlman can cut off or reduce the supply at his In Fig. 5is Shown a branch pip'e 2O leadf .its function is the saine, xand theglass Ais' kept cleaned byfa light-owfof warm eoinpressed air, or if thevalve 17 has vbeen closed and the glass of the headlight has become.

clouded, it may be cleaned by turning on lthe air at will.

I consider the use of a pliable pipe espeeially important,Y because,even if the nozzles l and 2 are not swiveled as ,suggested l0 above,they` may be bent slightly so that the tips 3 can be directed toward theglassfl() 'at the1 proper angle.` Soiiietiiiicstlie saslies are fixed,but usually they slide. Occasionally theyswing, and it" in swingingkthey strike one ol the nozzles, the saine can be deflected it it isot'pliable pipe, or could be turned. if it isrswiveled in the holt. Any

, appropriate foi-m' of swivel may be' eniployed, and I do not considerit necessary .to show its details.

It will be revident that without departing from the spirit of thisinvention it may be applied to the windshield of an automobile and thelike for keeping the samefree of dirt, snow, moisture, ctc. In-suehcase, there' lcuinulation of moisture (nor of dirt)y upon the inside ofa. windshield.

That I claim isz' i l. 'In a device of the class described, .thecombination with a boltgpassing through a window frame and having. abore through its body` and laterally out its hea'd,-aiid means Yforsupplying compressed air to the vlateral bore; of curved nozzles eachhaving one end tast in one extremity ofsaid boie and atip at its other,end directed toward the glass of the window. c
